This study demonstrates optically and spatially band-tunable color cone lasers based on DDCLC cells with a photoisomerizable chiral dopant. The band-tunability is attributable to the recovery of the helix of the CLC resulted from the trans-cis isomerization induced decrease of the helical twisting power of the chiral dopant.The more the chiral cis-isomers are produced, the larger the tuned lasing band is.

本文主要藉由在胆固醇液晶射中加入可光致同素构化亲手性材，使胆固醇液晶所输出的彩色锥角射波段可光调控及空间调控，其射输出波段可调控的机制是由於当同素构化反应产生后，光致同素构化亲手性材的HTP值低并造成胆固醇液晶距改变，藉此间接调控输出的射波长，同素构化的程愈高，胆固醇液晶所输出的彩色锥角射波段可调控范围也愈大。
